Ever found yourself in a situation where you needed to check someone's vital signs but couldn't quite remember the normal ranges? You're not alone. That's why we've created this comprehensive, easy-to-use cheat sheet to help you quickly reference normal vital signs. Let's dive right in.
Vital signs are essential for assessing a person's health status. They include body temperature, heart rate, respiratory rate, and blood pressure. Let's explore each of these in detail.
Body Temperature
Body temperature is a key indicator of a person's health. It's typically measured in the mouth (oral), ear (tympanic), or rectum (rectal).
Normal ranges vary slightly depending on the method of measurement:
Oral Temperature
Normal oral temperature is 97.6°F to 99.6°F (36.0°C to 37.5°C).
Factors like recent exercise, fever, or hormonal changes can temporarily raise or lower oral temperature.
Tympanic Temperature
Normal tympanic temperature is 99.3°F to 100.4°F (37.4°C to 38.0°C).
Tympanic readings are often higher than oral readings due to the measurement location.
Heart Rate
Heart rate, or pulse, is a measure of how many times your heart beats per minute. It's typically felt at the wrist or neck.
Normal heart rates vary with age and physical condition:

Resting Heart Rate
In adults, a normal resting heart rate is 60 to 100 beats per minute (bpm).
Well-trained athletes may have resting heart rates as low as 40 bpm.
Maximum Heart Rate
Maximum heart rate is the highest heart rate achieved during exercise. It can be estimated using the formula: 220 - age.
For example, a 30-year-old's maximum heart rate would be 220 - 30 = 190 bpm.
Respiratory Rate
Respiratory rate is the number of breaths taken per minute. It's typically measured by counting the number of inhalations over a set period.
Normal respiratory rates vary with age:
Newborns to 2-year-olds
Normal respiratory rate is 30 to 60 breaths per minute.
Infants and young children have higher respiratory rates due to their smaller lung size.
Adults
Normal respiratory rate for adults is 12 to 20 breaths per minute.
Respiratory rate can increase with physical activity, fever, or anxiety.
Blood Pressure
Blood pressure is the force exerted by blood against the walls of blood vessels. It's measured in millimeters of mercury (mmHg) and is expressed as two numbers, such as 120/80 mmHg.
Systolic pressure (the top number) is the pressure when the heart beats, while diastolic pressure (the bottom number) is the pressure between heartbeats.
Normal Blood Pressure
Normal blood pressure is less than 120/80 mmHg.
Blood pressure can vary throughout the day and can be influenced by factors like stress, exercise, and diet.
Hypertension Stages
Blood pressure can also be classified into different stages based on the systolic and diastolic readings:
- Normal: less than 120/80 mmHg
- Elevated: 120-129/less than 80 mmHg
- High Blood Pressure (Hypertension) Stage 1: 130-139/80-89 mmHg
- High Blood Pressure (Hypertension) Stage 2: 140/90 mmHg or higher
- Hypertensive Crisis: higher than 180/120 mmHg
Remember, these are just guidelines. Always consult with a healthcare professional for personalized advice. Now that you've got this cheat sheet, you're ready to take on the world of vital signs!
